During its half-century of existence, from its founding in 1952 until the present day, the knitwear manufacturer Yonetomi Seni Co., Ltd. has dedicated itself to the creation of beautiful sweaters. We have knit classic and quintessential sweaters, summer sweaters which are innovative and unconventional, and sweaters that upend the very concept of the sweater. Our determination to remain at the forefront of our industry is something which has defined our identity, and we continue to explore new possibilities in knit fabric creation, pouring all of our technology, ingenuity, and knowledge into our sweaters – and it is the sum of all these efforts which has led us to the present day. For Yonetomi Seni, “What is a sweater?” is a familiar query which has accompanied us throughout our history, and at the same time a question which we continually ponder anew. We have now taken it upon ourselves to focus our attention squarely upon this inquiry and see what answers await us as we delve into as-yet unexplored areas, presenting each of the answers we discover in our “This is a Sweater” series. We will continue to weave a story that begins with a single strand of yarn and culminates in beauty which is lasting, value which refuses to age, and a familiar feeling of comfort which will never cease to envelop us.
